Cabinet and wardrobe backs
Coordinate the complete carcass, groove or applied-fixing method, perimeter and intermediate support, service openings and visible interior face.
Thin supported furniture-part specification
Give cabinet backs and drawer bottoms their own part specification. We supply thin hardboard and cut parts with the actual face construction, finished size and orientation agreed for your furniture. Send the groove or rebate details and assembly drawing; a representative fit check connects the board thickness to the supported cabinet or drawer you are making.

Choosing your material
Begin with the supported furniture part and its assembly interface, then select the hardboard thickness, face and processing method.
A cabinet back can slide into a groove, sit in a rebate or fix onto a supported frame; a drawer bottom is captured by a different groove and hardware assembly. The drawing must state finished size, face orientation, fit allowance, support, fixing and quantity for each part.
Coordinate the complete carcass, groove or applied-fixing method, perimeter and intermediate support, service openings and visible interior face.
Define the groove, capture depth, finished size, drawer or frame dimensions, intended support, visible side and assembly sequence.
Fit a production-representative cut part, verify squareness and orientation, then protect thin labelled parts on continuous flat support.
CUZI MDF hardboard is offered in 1.5–5 mm thickness at 810–960 kg/m³. Choose the actual product within that range and pair it with the part support, drawer or cabinet construction and acceptance method in your furniture design.
Furniture-part matrix
Similar thin panels can perform different roles. Quote each cut part against the actual furniture interface and approval point.

Plan component setsSelected assembly example
This drawing selects a 400 × 450 mm clear drawer, 8 mm grooves, 2 mm total root clearance and a 3 mm nominal bottom. The separate back example selects a 600 × 720 mm carcass, 1 mm panel inset and 18 mm side/centre rails. These are nominal drawing inputs; actual completed dimensions, tolerances, allowances, support and connections follow your furniture design and fitted sample.
| Part or check | Selected inputs | Calculation | Production reference |
|---|---|---|---|
| Drawer-bottom cut size | Selected clear interior: 400 × 450 mm; each groove depth: 8 mm; total root clearance: 2 mm in each direction | 400 + 8 + 8 − 2 = 414 mm; 450 + 8 + 8 − 2 = 464 mm | Cut size is 414 × 464 mm for this selected centred assembly. Actual clear size, groove roots, panel tolerances and movement allowance determine the production drawing. |
| Groove capture at each edge | Selected root clearance: 1 mm per side; groove depth: 8 mm | 8 − 1 = 7 mm nominal capture | Check minimum capture over the actual panel and carcass tolerance stack, including assembly movement and any withdrawal path. |
| Completed thickness and groove width | Selected finished panel interval: 2.9–3.1 mm; actual groove-width interval: 4.0–4.2 mm | Minimum total clearance: 4.0 − 3.1 = 0.9 mm; maximum: 4.2 − 2.9 = 1.3 mm | This is total thickness-direction clearance, shared above and below the part according to its seating. Assign actual intervals to the completed product and trial the production groove. |
| Applied-back size and fixed-edge references | Selected carcass outer size: 600 × 720 mm; back inset: 1 mm on all edges | 600 − 2 × 1 = 598 mm; 720 − 2 × 1 = 718 mm | A selected fixing line 9 mm from the carcass edge becomes 9 − 1 = 8 mm from the back edge. The fastener and receiving material follow the actual assembly drawing. |
| Clear span between supports | Selected carcass width: 600 mm; side rails: 18 mm each; centred intermediate rail: 18 mm | (600 − 18 − 18 − 18) / 2 = 273 mm per clear bay | 273 mm is edge-to-edge support geometry. The complete cabinet assessment defines bracing, attachment, permissible use and actual support. |
| Same feature viewed from the reverse | Selected back width: 598 mm; opening centre in F01 view: X = 40 mm, Y = 60 mm; Ø20 mm | F02 left-origin view: X = 598 − 40 = 558 mm; Y = 60 mm | The physical D0 corner appears on the right in the reverse view. Give machining operations their own face and datum, and carry the same physical feature through both views. |
Trial the panel and the actual receiving furniture together. Groove width is compared with completed thickness, groove-root distance with cut size, and support span with the intended drawer or cabinet use. A finish or coating is included in the selected completed thickness; the actual sample establishes any extra build and the resulting fit.
Part and assembly schedule
Use these examples to plan panel sizes, then add the support, fixings, finish and quantities for each furniture part.
| Reference | Part or assembly data | Face and orientation | Order and fitted-sample record |
|---|---|---|---|
| D01 drawer bottom | Selected example: 414 × 464 mm; nominal 3 mm with selected completed interval 2.9–3.1 mm | F01 faces contents; F02 faces the underside. The selected example uses smooth F01 and the specified screen-pattern F02. | Record clear drawer size, four groove roots/positions, insertion sequence, capture, hardware and any bottom support. |
| B01 applied cabinet back | Selected example: 598 × 718 mm; nominal 3 mm; selected 1 mm perimeter inset | F01 faces the cabinet interior; F02 faces the accessible rear. D0 and top direction identify the same physical edges. | Record perimeter/intermediate rails, opening Ø20 at F01 (40,60), actual fixing schedule, panel overlap and wall clearance. |
| G01 groove or rebate | Actual width, depth, position and remaining receiving-member section | Define the viewing face and reference edge on the carcass or drawer member. | Carcass/frame groove machining belongs to its named order line. Panel supply and receiving-furniture work are itemized separately. |
| S01 support and connection | Actual perimeter/intermediate members, brackets and their locations | Record the supported underside or rear and the receiving substrate for each connection. | List included supports, nail/staple/screw type, head/crown, length/penetration, edge distances and spacing, plus any pilot requirements. |
| F01 / F02 supplied surfaces | Actual raw, coated, printed or faced condition and finished thickness | Retain labelled photographs of both sides and the installed direction; match the actual product sample. | State factory finishing and buyer finishing as separate stages, including the contact face and reverse treatment for a bond or coating trial. |
| P01 furniture-set pack | Actual part quantities per cabinet/drawer set, revision and spare quantity | Labels and stack order preserve F01/F02, top direction and part identity. | Reconcile cut parts and any ordered accessories to one set; list covers, flat support, separators and receiving sequence. |
Record dimensions from named physical references. The selected applied back has a fixing line at X8/X590 and Y8/Y710 in the F01 view; the actual nail, staple or screw detail defines receiving material, penetration, head/crown, spacing and edge preparation. Support dimensions describe the member arrangement; record the agreed complete-cabinet or drawer assessment with the fitted sample.
For repeat orders, retain labelled photos of both faces, the actual groove/rebate section, supported assembly and connections. Connect the measured part, drawing revision, sample ID, acceptance conditions and BOM. The Hardboard sheet buying guide helps you specify faces, sizes and packing. The Hardboard, MDF and HDF comparison guide explains product selection, while the cut-list guide explains how to identify MDF components; Hardboard formats and tolerances use their own order record.

View productBuyer questions
Use these answers to connect the selected sheet, fitted component and repeat furniture order.
Yes, for supported cabinet and wardrobe backs with the groove or applied fixing, perimeter support, panel size and assembly method defined. Specify the actual smooth and reverse faces, finished dimensions and thickness tolerance. The complete cabinet design determines the required support and bracing performance.
It can be considered for drawer bottoms supported by the released drawer construction. The designer should define drawer size, contents, groove capture, front and back joints, support and hardware. A representative drawer should be assembled before repeat production.
The order must identify the visible face. Some hardboard has a smooth face and a screen-pattern reverse; other constructions may differ. Record face and reverse in drawings, labels and packing instructions so installers receive clear orientation.
Define the actual groove width, depth and position, hardboard thickness and tolerance, any coating or laminate build, finished panel size, insertion allowance and assembly sequence. Approve the fit using production-representative materials.
Support parts continuously on a flat base, use clean separators and top protection, protect corners and edges, control strap positions and pressure, keep packs dry and label each furniture or part group while keeping the thin sheets flat and supported.
Send cabinet, drawer or frame drawings; part IDs and quantities; finished dimensions; thickness and tolerance; face/reverse and finish; groove, rebate or fixing details; holes and cut-outs; first-fit plan; labels, packing, destination and timing.
Yes. Our product samples are free and usually available from stock. Tell us which board and finish you want to compare, including the actual face and reverse, thickness and fit in your groove. You pay the courier charge, which can be credited against the formal order amount. We confirm sample availability, preparation and estimated transit time before dispatch.
Start from the actual clear distance between the drawer's inner faces, add the groove depth on both sides and subtract the agreed total clearance to the groove roots. In the selected example, 400 + 8 + 8 − 2 gives 414 mm and 450 + 8 + 8 − 2 gives 464 mm. When centred, 1 mm root clearance on each side leaves 7 mm nominal capture. Production dimensions also include panel/carcass tolerances, movement, insertion and any extra support.
Support span is measured between the actual supporting edges. A selected 600 mm carcass with two 18 mm side rails and one centred 18 mm intermediate rail gives two clear bays of (600 − 18 − 18 − 18) / 2 = 273 mm. The complete furniture design and assessment establish the suitable support, connection, use and load; this calculation describes geometry.
Name F01, F02, the physical D0 corner and the top edge. In the selected 598 mm wide back, a hole centre at X40/Y60 in F01 appears at X558/Y60 from the left edge in the F02 view. D0 remains the same physical corner and appears on the right in that reverse view. Dimension each face-specific operation from its named view and datum.
We itemize the actual Hardboard sheet or cut parts, product/finished thickness, dimensions, faces, openings, supplied finish, part IDs and quantities. The order also names any included support, fittings or accessories and the furniture operations completed in your workshop. A first fitted sample, current drawing, flat-supported pack and BOM keep the repeat set aligned.
